This 32GB DDR4-3200 Registered ECC RDIMM is engineered for enterprise servers, delivering the data integrity essential for virtualization and in-memory databases through its ECC and registered signal buffering. Its dual‑rank x8 configuration maximizes memory bandwidth per channel at a low 1.2V operating voltage, while the CL22 latency ensures efficient access in dense, multi‑DIMM configurations.
1. A 32-gigabyte capacity allows a single server to host more virtual machines and larger in-memory databases, directly raising consolidation ratios without sacrificing performance.
2. DDR4-3200 data rate delivers the sustained bandwidth required to keep modern multi-core server CPUs fed, preventing memory bottlenecks during heavy analytics or transactional workloads.
3. Error-correcting code protection automatically detects and fixes single-bit memory faults, preventing silent data corruption that could otherwise crash mission-critical enterprise applications.
4. Registered signal buffering stabilizes command and address lines across high-density configurations, enabling fully populated memory channels without compromising 24/7 operational reliability.
5. Dual Rank x8 organization interleaves accesses across two internal rank groups, increasing effective concurrency and delivering more consistent throughput under memory-intensive virtualization.
The Samsung M393A4G43AB3-CWECO is a server-grade DDR4-3200 Registered DIMM engineered for mission-critical enterprise environments. Its four defining characteristics directly address the real-world challenges faced by IT architects running virtualized clusters and in-memory databases.
The 3200 MT/s speed with CL22 latency delivers the sustained bandwidth that a hypervisor needs when juggling dozens of virtual machines, ensuring responsive performance even under heavy consolidation. More importantly, the ECC engine continuously corrects single-bit errors caused by cosmic radiation or electrical noise. In a financial trading database held entirely in RAM, a silent bit-flip could corrupt a transaction record; ECC transforms that from a business risk into a non-event. The registered signal buffer isolates the memory controller from the electrical load of the DRAM chips, allowing you to populate all DIMM slots with 32GB dual-rank modules without sacrificing signal integrity or clock speed. For a virtualization cluster targeting maximum VM density, this means scaling to terabytes of reliable memory while avoiding the boot failures and instability that plague unbuffered designs. Finally, the dual-rank x8 organization interleaves access across internal banks, boosting effective throughput for analytical database queries that stream large datasets. This module does not just store data—it protects, stabilizes, and accelerates the real-time workloads your business depends on.
General Virtualization
Deploy one 32GB RDIMM per memory channel on a dual-socket server (e.g., 16 modules for 512GB) to provide balanced bandwidth for hypervisors and guest VMs. This configuration runs at the full 3200MT/s and leaves free slots for future expansion without sacrificing performance.
In-Memory Database
Maximize capacity by fully populating all channels with one module per channel (e.g., 24 modules total for 768GB on a 12-channel platform) to host large database instances entirely in RAM. The registered ECC design ensures operational stability for transaction-heavy workloads, and using dual-rank x8 modules boosts per-channel density without steep frequency drops.
High-Performance Computing
For maximum memory bandwidth, install exactly one 32GB RDIMM per channel across both processors (16 DIMMs in an 8-channel-per-socket system) to achieve 512GB at 3200MT/s. Avoid populating a second DIMM per channel, which could force a speed reduction to 2933MT/s or lower; this keeps latency predictable for tightly coupled parallel simulations.

Q: Can I mix this M393A4G43AB3-CWECO with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged in server environments. Mismatched modules can cause instability, timing conflicts, or even no POST. For guaranteed reliability, use identical sticks from the same manufacturer batch.
Q: Is this memory compatible with my system?
A: This DDR4-3200 ECC RDIMM is designed for servers using Intel Xeon Scalable or AMD EPYC platforms. Verify your motherboard specifically supports 1.2V, 288-pin Registered ECC memory at this speed and capacity.
Q: What is the recommended DIMM population order for optimal performance?
A: Always consult your server motherboard manual. Typically, populate DIMMs in groups of eight, starting with the white or blue slots per memory channel to balance interleaving and maximize bandwidth for Dual Rank x8 configurations.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC memory, it adheres to strict JEDEC specifications (DDR4-3200 CL22) for maximum data integrity. Overclocking features like XMP are not supported to ensure 24/7 stability.
Q: What warranty and typical failure rate can I expect?
A: This module is covered by a 1-year warranty. Enterprise RDIMMs have an extremely low annualized failure rate, often below 0.1%, due to rigorous component screening and Samsung's heavy testing for mission-critical workloads.
